Air Knockers vs AirSweep:
Pros and Cons

Air knockers are like pneumatic hammers.

Compressed air pushes the piston against the vessel wall and makes it vibrate. The shaking and agitation loosen material that cling to the vessel walls.

Air knockers (or air hammers) are used to:

  • Shake off excess powder
  • Remove products from molds
  • Remove water and splatter
  • Prevent adhesion of workpieces

AIR KNOCKERS VS AIRSWEEP

Air Knocker

AIRSWEEP®

Functionality

Air Knocker

  • Air knockers induce vibration energy to the vessel wall, which transmits into the material to shake it loose

AIRSWEEP®

  • Directs smaller, equally powerful bursts of air along the bin wall, lifting material off the wall and back into the flow stream
  • Eliminates bridging, ratholing, or sticking problems
  • Stimulates up to a 2.44 m (8 foot) diameter circle of material around each nozzle

Noise Level

Air Knocker

  • Air knockers can be extremely noisy

AIRSWEEP®

  • Makes a quick, ear-friendly “psst” or “pop”

Maintenance

Air Knocker

  • Metal and weld fatigue can occur due to vibration or hammering from piston air knocker. Wear and tear on vessel walls can be costly
  • Expensive to operate. Air knockers use a lot of air or power to operate

AIRSWEEP®

  • No damage, vibration, stress or wear to vessel walls
  • Uses as little as 10 CFM of compressed air or gas
  • Only needs inspection every 6 months, and replacement of parts after 1,000,000 cycles
  • Longest industry warranty – 7 years

Material Control

Air Knocker

  • Sticky material remains, and builds up over time on bin walls, even if bridging is controlled
  • Periodic shutdowns may still be required to clean bin walls, especially if cross-contamination is an issue

AIRSWEEP®

  • Each pulse of the AirSweep sweeps along the bin walls, preventing material from adhering to the sides, or building up
  • In general, full clean out of the bin occurs with each batch, ensuring first-in/first-out material flow with no cross-contamination

Are You Just Getting a More Expensive Hammer?

AIR KNOCKERS ARE NOT EFFICIENT FLOW AIDS

Air Knocker vs AirSweep

POOR MATERIAL CONTROL

  • Not effictive for all materials
  • Sticky residue can remain on walls
  • Does not promote first in/first out flow
Air Knocker vs AirSweep

EXPENSIVE

  • Metal fatigue damages the vessels
  • Uses a lot of plant air and electricity
Air Knocker vs AirSweep

INCONVENIENT

  • Causes worker stress and can affect hearing
  • Vessels still require periodic manual cleaning

  • Air Knocker vs AirSweep

    The AirSweep installation was pretty straightforward and I would absolutely recommend it. In fact, we are looking into expanding to use the system in other parts of our plant.

    John PappenheimMaintenance Manager, Bunge Milling

  • We are experiencing a 62.52% reduction in flour flush and 42.50% reduction in labor, all directly attributed to the AirSweeps…the flush material reduction alone is around $200K. Pretty awesome little devices!
